P0119 2017 Ford F150 Code - Engine Coolant Temperature Sensor 1 Circuit Intermittent
Quick Answer
The Engine Coolant Temperature (ECT) Sensor is a thermistor device in which resistance changes with temperature. Common causes include Low engine coolant level, Faulty Engine Coolant Temperature (ECT) Sensor, Faulty engine coolant thermostat. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0119 2017 Ford F150 Description
Thermistor-type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so varying the resistance of the passive sensor causes a variation in total current flow. The voltage that is dropped across a fixed resistor (pull-up resister) in series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor.
The ECT Sensor is located in an engine coolant passage and measures the engine coolant temperature. The PCM uses the engine coolant temperature input for fuel control and for cooling fan control. The ECT Sensor can be a threaded or twist lock type.
This Diagnostic Trouble Code (DTC) is set when the ECT circuit is intermittently open or shorted while the engine is running.
What are the Possible Causes of the DTC P0119 2017 Ford F150?
- Low engine coolant level
- Faulty Engine Coolant Temperature (ECT) Sensor
- Faulty engine coolant thermostat
- Engine Coolant Temperature Sensor harness is open or shorted
- Engine Coolant Temperature Sensor circuit poor electrical connection
How to Fix the DTC P0119 2017 Ford F150?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

OBDII code P0119 indicates an intermittent issue with the Engine Coolant Temperature (ECT) Sensor 1 circuit, which can affect engine performance and efficiency.
What are the common symptoms associated with code P0119?
Common symptoms include erratic engine temperature readings, poor fuel economy, engine overheating or running too cold, and possible check engine light illumination.
What could cause the P0119 code to trigger?
Potential causes include a faulty ECT sensor, damaged wiring or connectors in the sensor circuit, a malfunctioning engine control module (ECM), or issues with the thermostat.
How can I diagnose the P0119 code?
To diagnose P0119, check the ECT sensor and wiring for damage, test the sensor's resistance at various temperatures, and ensure the connections are secure. Use a scan tool to monitor the sensor data in real-time.
What repairs are typically needed to fix code P0119?
Repairs may involve replacing the ECT sensor, repairing or replacing damaged wiring or connectors, or addressing any issues with the ECM or thermostat.
Can I drive my 2017 Ford F150 with code P0119?
While it may be possible to drive the vehicle, it is not recommended as it can lead to poor engine performance and potential overheating, which could cause further damage.
Will clearing the code P0119 fix the problem?
Clearing the code may temporarily turn off the check engine light, but it will not resolve the underlying issue causing the intermittent circuit failure.
How much does it typically cost to fix an issue related to code P0119?
Repair costs can vary widely, but replacing an ECT sensor may range from $100 to $300, while repairing wiring issues can cost more depending on the extent of the damage.
Is P0119 a serious code that needs immediate attention?
Yes, P0119 indicates a potential problem with the engine's cooling system, which can lead to overheating and serious engine damage if not addressed promptly.
